Obtain User ID in ContextListener

What do you really want to accomplish here ?  
Obtain the username in the file carsContextListener.java


What is hardcoded ? Which user ? Please show us that code.
//code below


 public void contextInitialized(ServletContextEvent contextEvent) {
            try{
                  String fileSeperator = System.getProperty("file.separator");
                  
                //FIXME: the user is hardcoded, need to get an actual session attrib
                contextEvent.getServletContext().setAttribute("user", " rrz@871311");

I think if you're trying to work with the "current user" inside the ServletContext initialization you probably have the wrong design in mind.

The ServletContext is a single context shared by all Servlet and created at startup.  It shouldn't be used to store user specific information.

You probably should instead be implementing a Servlet (not a ServletContext) - which is initialized to handle an individual request (e.g. a page load) and so has the idea of a "current user" (or current session).  That Servlet could then make use of the ServletContext to get work done if necessary (e.g. gaining access to a database which has connections stored in the context).

Hope that helps,

Doug
